Castelldefels, Spain

With a population of 70,057, Castelldefels is a suburban haven for wealthy Barcelona residents, not a haven for the average expat. The town is known for its long beach and affluent residents, including famous athletes, but also faces persistent bureaucratic headaches. Transport links are decent, with two train stations and bus routes, but the 2010 tragedy where 12 young people were killed at a railway crossing highlights safety concerns. Overall, Castelldefels caters to the elite, not the everyday expat.
